Can't do the "run script" part due to login error

But something must have changed with version 3.4. I want to migrate from local SQL to SQLAzure and everything works until the part where I need to "execute script against target". Then I get a login error because it tries to login to
SQLAzure using my local credentials. The error is something like "Unable to connect to SQLAzure, using <domain>\<username>. Point is, that i don't want it to connect using <domain>\<username> (integrated security)
but instead use the Azure-specific username/password.

It does use the specific credentials to query SQL azure for the list of databases but when you select one and press <next> and accept the "Do you want to execute the script against target?"... you get the error since it now ignores the specific
credentials and use your domain (integrated) credentials... ?

If you do not specify a specific database on the connection screen, you will just list all of the databases and be able to select your target database or create a new database. I will fix the issue of connecting to a specific database in v3.4.1.
